Compute the middle surface strain

Reference no: EM131355824

Compute the strains ∈_x, ∈_y, and γ_xy at the interface between the 45° and -45° laminae above the middle surface by using the results of case (b) of Exercise 1 and (6.23).

Exercise 1

Consider a [+45/ - 45]S laminate with the material properties of Exercise. Compute the middle-surface strain ∈⁰_x, ∈⁰_y, γ⁰_xy

and the curvatures κ_x, κ_y, κ_xyfor the following load cases

(a) N_x = 1000 N/m; all remaining components are equal to zero

(b) M_xy = 1 Nm/m; all remaining components are equal to zero
